Migrating Doximity’s iOS Newsfeed to SwiftUI Without Disrupting Users or Development (opens on the source site)
Doximity ·
The Newsfeed is one of the most-used features in the Doximity iOS app. It is the first thing many users see when they open the app. For doctors checking in between patients or residents catching up during a break, it has to be fast and efficient. Those expectations defined success for the migration. Feature work had to continue, analytics had to remain reliable, and the experience had to remain familiar to users even as the underlying implementation changed. We approached the migration less like a rewrite and more like a controlled rollout. We moved one section at a time, kept the UIKit and…
Leveraging AI to build a faster iOS CI system (opens on the source site)
Every iOS pull request at Thumbtack used to wait 30 to 40 minutes for Continuous Integration (CI) — sometimes over an hour on Fridays. We built Smart Test Selection (STS) to cut that in half. Here’s how.I’m a Senior Software Engineer on the iOS Infrastructure team. We own the CI/CD pipelines, build tooling, and shared frameworks that keep Thumbtack’s apps shipping reliably. We also build AI-powered developer tooling — 35+ AI Agent Skills, MCP integrations for Jenkins, Figma, Firebase, and Xcode — that help the broader iOS team ship faster.Over the past few quarters, we built Smart Test…
Revamping Myntra App Analytics persistence with KMP and SQLite (opens on the source site)
Myntra ·
IntroductionIn the dynamic landscape of e-commerce, data is the bedrock of decision-making, and app stability is the foundation of user experience. At Myntra, where millions of users engage with our platform daily, ensuring the reliability of both is paramount. This necessity drove us to re-architect a critical piece of our infrastructure: the persistence layer of the Myntra app’s analytics SDK. This post details our journey of augmenting our legacy analytics SDK with a robust new persistence engine backed by SQLite[1], achieving significant gains in app stability and data…
Keeping Meeting Apps Alive in the Background on iOS and watchOS (opens on the source site)
Building an app that records meetings, generates transcriptions, and produces AI analysation sounds straightforward – until you try to make it reliable while the user goes in and out of your app, takes calls, plays music, or checks notifications. This post walks through how we handled background recording and post‑recording processing on iOS and watchOS […] The post Keeping Meeting Apps Alive in the Background on iOS and watchOS appeared first on RisingStack Engineering.
XcodeGen and the quest to modularize the Wealthfront iOS app (opens on the source site)
Every iOS application starts as a monolith. Xcode’s default project structure places all source files, resources, and build configuration into a single module (or target, for all the iOS devs reading this). For small apps, this works fine. For a 10+ year old financial application with roughly 2,000 Swift and a handful of Objective-C files,... Read more
Enhancing Myntra App performance: Transitioning from GIFs to Videos (opens on the source site)
Myntra ·
IntroductionIn the fast-paced world of e-commerce, every millisecond and every pixel counts. At Myntra, where visual content drives discovery and engagement, we embarked on a critical mission: to revolutionise how animations are delivered in our Android and iOS apps. This journey led us to transition from the ubiquitous GIF format to more efficient video formats, unlocking significant performance gains and a superior user experience.Background on GIFsThe Graphics Interchange Format (GIF) has been a widely-used format for looping animations since its introduction in 1987. Its simplicity and…
Apply blur to iOS status bar in PWA (opens on the source site)
Update August 2026: This workaround no longer works on recent iOS versions. WebKit changed how standalone PWAs handle the status bar area. The fixed overlay positioned outside the viewport no longer renders under the status bar. I haven't found a workaround for this yet. If you find a solution please let me know. On my current project, I'm making a Progressive Web App (PWA) and I was really annoyed that the status bar on iOS was completely transparentAlthough the option is called black-translucent. When the content scrolls behind it, it blends with the status bar elements, and it doesn't look…

Scaling iOS at Bumble: Part 3/3 — Results and Developer Quality of LifeRecapThis is the third and final post in a series on our 2022 & 23 build and project management overhaul. We investigated whether one (or none!) of Swift Package Manager (SPM), Tuist or Bazel would be the tool to overcome our project scaling challenges.In the first post we explained the state-of-play coming into this project. In the second we discussed the results of our proofs of concept. In this post we will explain our conclusions, and talk about the migration project itself.The decisionWe chose TuistIt shouldn’t be…

Scaling iOS at Bumble: Part 2/3 — The AssessmentRecapIn our previous post we discussed how we came to be investigating project and build toolchain replacement solutions for our iOS codebase at Bumble Inc. We began executing proofs of concept for Swift Package Manager (SPM), Tuist and Bazel.The ProcessOur investigative process for each tool was performed in roughly the same manner:1. OnboardingWith the exception of some light use of SPM as a third-party dependency manager, no-one on the team was fully fluent with any of the tools. This meant that at first, we needed to learn the basics, which…

Accelerate iOS Development Using Deep Links (opens on the source site)
Doximity ·
Do you work on a large app with lots of deep links and dynamic content? This article will show you how to manage and leverage those deep links so you can spend more time coding and less time navigating the app. Here on the News team at Doximity, we have lots of content to manage, including articles, comments, and collections of articles. The problem compounds when considering that articles have a lot of different variations, and some of those variations are uncommon. The variety can make it hard to test the entire app, and a real pain when trying to debug a problem on a specific piece of…

iOS Receipt Validation: Understanding and Troubleshooting the Original App Version Field (opens on the source site)
Setting the stage with a use case for checking the original_application_version The task appears to be simple. Suppose that… You have an existing app on the app store that’s currently at version 1.2 You want to shift to the “freemium” model by implementing in-app purchases starting with version 1.3 You want to be fair to previous-purchasers of my app (anyone who downloaded the app between version 1.0 and 1.2) Therefore… You want to check to see if someone originally purchased version 1.2 or below of your app so that you can “grandfather them in” To figure this out, you’ll need to implement…
4 Reasons Your iOS App Is Crashing (opens on the source site)
CPU cannot execute an instruction Sometimes we developers don’t play fair with the CPU. Suppose that I wrote some code that ended up telling the CPU to divide by zero. That’s… impossible… for you and the CPU. iOS is ensuring its own stability iOS may be enforcing a fundamental requirement or policy for its own stability. Apple isn’t going to let developers wreck the overall user experience of iOS. Examples: Your app takes forever to launch Your app is using too much memory iOS will opt for killing your app to protect the user’s overall iOS experience. Swift runtime is preventing failure There…
4 Things You Should Never Do When Debugging iOS Apps (opens on the source site)
Never change code without reproducing the problem first Reproducing the problem is a critical first step in debugging. Before you start scouring your code… Before you start setting breakpoints… Before you start using tools or changing things… See if you can cause the bug to happen again. The goal of this exercise is to confirm that the problem is consistent. Reproducing the problem helps you clarify the conditions that are present when the bug happens. Do your best to clearly state what’s going on – I even write it down sometimes to document the problem and make sure I’ve got it pinned down.…
